Summary:

This role helps in ensuring security quality and operational readiness of PCG (Product Cybersecurity Group) products before deployment to market and maintaining alignment to cybersecurity goals throughout the product lifecycle in efforts to meet the customers' goals. Product cybersecurity resilience is an ongoing effort that is expected to carry alongside R&D operations teams for identification of new product changepoints and ensure that cybersecurity goals of the product are upheld throughout the product lifecycle while it is with customer. Throughout the process, technical product knowledge is applied to evaluate residual risk at product launch, and maintenance of that risk throughout the product lifecycle. This technical knowledge is leveraged in Operational Readiness, Operations Management, Vulnerability Assessment, Vulnerability Validation, Countermeasure Validation, and Continuous Testing and Monitoring activities of the scoped products.

Essential Functions:

As an engineer on the Product Cybersecurity Group supporting Operational Readiness, Operations Management, Vulnerability Validation, and Continuous Testing and Monitoring capabilities will be responsible for:

• Performing technical review assessment of products to identify potential risks as assigned, per process.

• Documentation of, and Confirmation of countermeasures for risk reduction of identified items as assigned, per process.

• Documentation of post-launch remediation plans as necessary, and work with necessary teams to ensure timelines are met accordingly as assigned, per process.

• Develop and maintain risk communication materials for product management for new product launches based on information repositories as assigned, per process.

• Execute of Product Cybersecurity Resilience processes for Launch Readiness activities as assigned, per process.

• Performing Vulnerability Validation as needed.

• Performing Continuous Testing as needed.

• Developing custom tooling (HW/SW) as needed for validation efforts.
